Susan Mcelwain: Less than a minute before the Flight 93 crash rocked the countryside, she sees a small white jet with rear engines and no discernible markings swoop low over her minivan near an intersection and disappear over a hilltop, nearly clipping the tops of trees lining the ridge. [Bergen Record, 9/14/2001] She later adds, Theres no way I imagined this planeit was so low it was virtually on top of me. It was white with no markings but it was definitely military, it just had that look. It had two rear engines, a big fin on the back like a spoiler on the back of a car and with two upright fins at the side. I havent found one like it on the Internet. It definitely wasnt one of those executive jets. The FBI came and talked to me and said there was no plane around. But I saw it and it was there before the crash and it was 40 feet above my head. They did not want my storynobody here did. [Mirror, 9/12/2002]
Not based on the witness's description. An AWACS is a military version of the Boeing 707. I don't think she was describing a 707 flying beneath a power line.
